Embodiment Construction

[0026] The present invention will be further described below in conjunction with specific examples.

[0027] See attached figure 1 And attached figure 2 As shown, in this embodiment, a dynamically adjusted modular multi-line control method includes an indoor unit and an outdoor unit, wherein the outdoor unit is composed of multiple parallel outdoor units, and each outdoor unit corresponds to The output capacity can be the same or different, which is determined by the actual equipment conditions; the indoor unit includes multiple parallel indoor units, and the capacity requirements of each indoor unit are determined by the user's operation.

[0028] The following further explains the modular multi-connection control method of this embodiment.

[0029] The control method of the present embodiment includes the following steps:

[0030] Step S1. When the power is turned on and started, calculate and confirm the capacity demand Q of the indoor unit 内 , that is to calculate the...

Abstract

The invention discloses a dynamically-adjusted module type multi-split air conditioner control method. The method comprises the following steps that S1, when a multi-split air conditioner is electrified and started, the indoor unit capacity requirements Q-indoor unit generated in the electrifying process are calculated and confirmed; S2, the operation states of all outdoor units are detected and judged, the output capacity capable of being provided by each outdoor unit in the normal state is calculated and confirmed, then all the outdoor unit combination modes capable of meeting the capacity requirements Q-indoor unit are obtained, wherein each combination mode comprises at least one outdoor unit; S3, all the combination modes meeting the requirements are classified on the basis of the number of the outdoor units needing to be started; S4, the combination mode with the optimal energy efficiency ratio and the minimum category is selected, and then the corresponding outdoor units are started to perform weighted average operation; and S5, in the operation process, the indoor unit capacity requirements Q-indoor unit are monitored and calculated in real time, the indoor unit capacity requirements are dynamically monitored, the proper combination mode is dynamically selected, and the corresponding outdoor units are started to perform weighted average operation according to the reselected combination mode.

Description

technical field [0001] The invention relates to the technical field of multi-connection systems, in particular to a dynamically adjusted modular multi-connection control method. Background technique [0002] The existing parallel-connectable multi-connection unit will connect many indoor units when multiple outdoor units are installed in parallel, and the number of these indoor units to be used is uncertain. In addition, under different ambient temperatures, the indoor unit needs to be provided by the outdoor unit. The load requirements are also different. Therefore, when multiple outdoor units are connected in parallel, the number of outdoor units that need to be turned on in the system and the capacity that each outdoor unit needs to provide are different. [0003] Usually multiple outdoor units are connected in parallel, and the outdoor units are divided into 1# outdoor unit, 2# outdoor unit, 3# outdoor unit, and 4# outdoor unit. The usual practice is that only 1# outdoor...
